A. N. HERMAN. l DBYING RACK POR PHOTOGRAPHIU PLATESe APPLIOATIOI I'ILED nl n, 1999.

Panntq Sept 13,191.0.'

fizffff x :i5 As shown in the draw' it, a Aciti'z"e"n fof-'theUnited States, and a ident'of-"jNewark, in the county of Essex dfStiite' off-NewJers'ey, have made a cerf'new'ad useful' Invention in Drying- R cksffor Photographic Plates, of which lie llo'win fis a description.

y invention relates-to apparatus for dryingphotographic plates and its object is to ..1-pr6vide`means whereby photographic lates, `.1'2a-Lifterr'' 'h"ingbeen develo ed, tix and j'wash" ay be easily an quickly dried. washing, the drying of a photographic 1115i pl'ateis often -a very tedious` and slow matter. Accordingly, I provide' a rack comsihgfaseris". of' holders in which the ho I plates can be readil placed, l d holders being rapidly revo ved by a rnotor or other convenient means,

. fvheiieby'thewater adhering to the film on i fthejplates is lthrown oil by centrifugal force 'and-,thefplates quickly dried.

" Otherfohjects of my invention are to pro- ;125 vide; improved details of construction as described-:inthe following specification and particularly pointed out in the claims.

Attention 1s hereby called to the acoornpanyingv drawings forming part of this 43 0 specification, in which- -Figure 1 represents a partial lan view of my improved apparatus, and 1g. 2 rep- -resentls a vertical cross section of the same taken on line 2--2 of Fig. 1.

` a vertical shaft 1 is provided, which sha is supportedin and extends above a box or case 9. 1n which any Vsuitable motor (not shown) for revolving the same may be placed. This motor is preferably a spring motor, but any convenlent -form may be used. As shown in the drawings, the handle 3 is provided for winding the spring motor which is supposed to be contained in the box 2. The rack for holding the plates to be dried may be fastened to the vertical shaft 1 in any convenient manner. In the form shown in the drawings, a sleeve 4 is secured to the shaft 1 as by means of the set screw 5. The sleeve 4 is provided with a series of lugs 6 arranged radially around it. These lugs 6 are bifurcated to embrace the plate holders 7 which may be soldered in place between the forks of the lugs 6. It is to be understood that the plate holders 7 may be se- Speolllcation of Letters Patent.

cured to the lugs 6 in any other convenient manner, and also that the sleeve 4 might be dispensed with if desired, the late holders being secured directly to the s iaft 1. The form disclosed is thought preferable, howen ever, in order that the various parts may be the more easily removable. The plate holders 7 are referably disposed at an angle to the verticai)shaft i, as indicated in Fig. '2

of the drawings by the plate holder 7', 65 which is shown in dotted lines, the same being understood to be situated in a plane lying at ri ht angles to the surface of the drawing. 'he axes about which the various plate holders are inclined, as described, are 10 radially disposed about the shaft 1, and are continuations of the lu 6 thereon. The plate holders 7 are pre erably sheet metal plates having a' lower edge 8 and an outer edge 9, and each of the same bend upwardly and forwardly respectively to form bearing surfaces for the plates and to prevent the plates from being thrown ofi by centrifugal action in the rotation of the holders. A channel or passage 10 is provided in the 80 lower outer corner of each plate holder for the passage of whatever water on the plates is thrown olf by the centrifugal action, and this passageway 1f) may be provided, as shown, by cutting away the flange 9 a short 85 distance from its junction with the lower flange 8. A trough or tank 11 is provided beneath the rotary plate holder to catch whatever water is thrown olf. The bottom 12 of this tank or trough is inclined as 90 shown toward the spout 13, from which the water contained in the receptacle 11 may be allowed to drip into any convenient receptacle.

In operation, the plates to be dried are placed on the plate holders 7 with the Glass sideof the plates against the surface of the holder, the ilrn side of the plates being exposed to the action of the air as the rack 1s revolved. Owing t\ the inclination at 100 which the plates are preferably disposed, the air passes freely over the surface of the plates in their revolution, drying the same while the centrifugal action caused by the revolution of the plates tends to throw off the drops of waterfrom the film.' It is to he noted that owing to t-he inclination of the plates, the air is caused to circulate over the film surface of the plates during their revolution in much the same manner as air asses over the surface of a revolvin fan lade.v It is, however, to be understoo that l.1232, :plaies-.might 'be disposed vertically alfthoiigmas stated, I-prefer to incline them at anvangle, as shown.

Having now described my invention, what I claim and desire to secure by Letters Patent of the United States-is as follows:

1. In a drying rack, in combina-tion, a shaft, a plurality of plate holders radially disposed about and secured to said shaft, and means for revolving said shaft, substantially as described.

2. In a drying rack, in combination, a revoli'ible shaft and a. plate holder comprising a flat plate disposed radially to said shaft and secured thereto at one edge, substantially as described.

3. In a drying rack, in combination, a revoluble support, a plate holder mounted on said support, and means supporting said holder at an inclination to the axis of said sup rt, the axis to which said holder is inclined intersecting the axis of said support, substantially as described.

4. In a drying rack, in combination, a .'revoluble su port, a plate holder, compris- .ing a dat piiite, mounted on said support, and'means supporting said holder at an incli'nation to the axis of said support, an element of said holder intersecting the axis of said support, said holder being provided with means for retaining a photographic plate thereon, substantially as described. .35

-5. In a drying rack, in combination, a

a plurality of plate holders each inclined at an angle to the axis of said sli the axes about which the said holders inclined being radially disposed to the said shaft, :in d means for securing said holders to the said shaft, substantially as described.

6. In a drying rack, in combination, a shaft, a pluralit of plate holders each inclined at an ang e to the axis ot said shaft theaxes about which the said holders are; inclined being radially disposed to the said shaft, means 'o1' securing said holders to the said shaft., and means for revolving said shaft, substantially as described.

T, In a drying rack, in combination. a revoluble support, a plate holder mounted radially on said support and consisting of a flat plate having the lower and outer edges bent upwardly and forwardly respectively to hold a plate, and means for revolving said support, substantially as described.

8. Iii a drying rack, in combination, a. i'evoluble support, a plate holder mounted radiallyr on said support and consisting of a flat plate having the lower and outer ges bent upwardly and forwardly respectively to hol a plate, said outer edge being so formed at its lower end as to provide a pas sage for duid thrown od centrifugallv, and n ieans for revolving said support, sifbstantially as described.
